3 Claims. (01. 1 01-228) My invention relates to an automatic printing with a folding machine, or reinforcing strip madevice and more particularly to such a device used chine, so as to print symbols on said sheets. in combination with certain machines, such as Other objects and features will more full apfolcling and cutting machines, and reinforcing pear from the following description and accom- 5 machines. panying drawings, in which; Fig. 1 is a front view One of the difficulties now experienced in the in elevation; Fig. 2, a side View; Fig. 3 a side view manufacture of books, is the ascertaining of the of a roller, and Fig. 4, a sectional view in elevafront and back end sheets, after they have been tion showing the invention attached to, and. in treated with the reinforcing slip or strip. combination with, a machine.

There is also a posfeed ink to a wick 24, located near the ink supsibility of placing the wrong and sheets in the ply; and depending therefrom so as to touch wrong book, and the invention also overcomes roller 5, and keep it supplied with ink. As roller this mistake. 5 rotates ink is drawn thereon from the wick.

Another object of this invention is the provi- A thumb screw regulates a pin 25 engaging a 55 sion of adevice adapted to enter into combination nipple 26. A detailed description of the well is not thought necessary since it is in general use, and well known in the art.

The bracket is pivotally connected to a support 27 by a bolt 28 provided with a nut (not shown). Said support 27 resembles, in shape, a chair, and has a back 30 through which a screw 31 is disposed and secured thereto by a nut 32. A spring 33 fits over said screw, one end bearing against a tension nut 32, and the other end, which extends beyond said screw, is seated in an aperture 34, in said bracket.

The support is also provided with a pair of legs 35, one of which accommodates a set screw 36, which is adapted to secure the device to a cross-bar 3'7 on (in this particular instance) a folding and cutting machine 38, a portion of which, is only shown.

The machine 38 is provided with a plurality of rollers 39 upon which are respectively mounted, belts 40 that convey and eject the end sheets from said machine. The ejected sheets are deposited into a container, not shown, and then taken to be treated with reinforcing slips.

A roller 41 provided with rubber rings 42, in spaced relation to each other, has adjoining it a roller track 43 upon which a belt is connected, similar to those described for rollers 39. The rings 42 abut rings 1'7, and transmit motion thereto. The roller 41 is rotatable on an axle 44, and both are substituted for the usual machine roller 39, and secured to the bracket 39'.

The bracket, as heretofore described, is pivotally connected to the support, and the spring 33 tends to force the former downwardly, thereby assuring proper pressure of roller 8 against roller 41 so as to provide a clear symbol. The tension nut 32' may be employed to obtain proper tension. Free axial movement of the bracket is also permitted to compensate for material passing between said rollers, as well as unforeseen complications.

The device functions as, follows: As the belt moves, it actuates roller 41, which is in operative relation with roller 8, and transmits motion thereto. The stamp and blank on roller 8 engages roller 6, and the latter, in turn, engages roller 5. The wick is fed with ink from the well, and spreads it upon roller 5, and such is transferred to roller 6 and supplied to the stamp.

As the end sheets are being conveyed by the belt, they pass between rollers 8 and 41 on rings 17 and 42, and the stamp prints a designating symbol thereon. This invention may be used upon various machines, as for instance; it may be combined with a machine generally used for putting reinforcing strips on the end sheets.

Having described my invention, I claim:

1. The combination in a folding and cutting machine consisting of a support secured to said machine; a bracket pivotally connecting said support, a plurality of ink-rollers mounted rotatably in said bracket; a roller stamp in said bracket in operative relation with said inkrollers; a roller engaging said roller stamp, and a conveyor belt engaging said last named roller to transmit motion to aforesaid rollers.

2. In a device of the character described consisting of a support, a bracket pivotally connecting said support; a plurality of ink-rollers mounted loosely in said bracket; means for supplying ink to said rollers; a stamp-roller, a roller engaging said stamp roller, and a conveyor belt engaging said last named roller and adapted to be actuated to transmit motion to aforesaid rollers.

3. In a device of the character described consisting of a support, a bracket pivotally connecting said support; a plurality of ink rollers mounted loosely in said bracket; means for supplying to said rollers; a stamp roller, a roller engaging said stamp roller and means engaging said last named roller and adapted to actuate same so as-to transmit motion to aforesaid rollers.
